Answers "should I become a team lead?" with the same 17-question test as the live tool at marian.coach: 6 dimensions (people appetite, letting go of code, ownership beyond your tickets, translation & saying no, motivation, org reality), a straight verdict — ready now / 6-12 months out / stay IC (and that's fine) — plus the top-2 gap dimensions with one concrete move each. Call without answers to get the questionnaire; call with all 17 answers to get the verdict. Built from 3,662 mentoring sessions.
Answers keyed by question id (q1-q17), each the 0-based index of the chosen option for that question (NOT a rating — option scores are calibrated and non-monotonic). Omit to receive the 17 questions with their options first.
Optional. A short description of your goal and why you are calling this tool. Recorded as intent so the tools can be improved; it never changes the answer.

}Build the case that gets your company to pay for leadership mentoring — everything on marian.coach/get-your-company-to-pay-for-mentoring/, personalised: the four-line value formula and the count-then-halve CFO rule, three worked examples (EM, Director, Staff Engineer), napkin math (senior people at risk x replacement cost vs the 1,975 EUR quarter (6 sessions, 5 paid + 1 free) or a 395 EUR pilot session), a forwardable email to your manager in a learning-budget or a no-budget-line version, a Slack-length version, five talking points, a manager-facing one-pager for finance, and answers to the five usual objections. English or Czech, tykani or vykani. Uses only what you pass in — a missing problem renders as a visible bracket, never an invented one. From 3,662 mentoring sessions at marian.coach.

Assess a software developer's market value: score 15 skills across 5 pillars (core craft, systems & judgment, impact & ownership, collaboration & influence, AI leverage), get a weighted total score, seniority level, and a 2026 Western-Europe gross salary estimate. Same logic as the live calculator at marian.coach. Unscored skills default to the level's baseline.
| Argument | Type | Description |
|---|---|---|
| level | string | Required. The developer's current (or claimed) level — sets pillar weights and baseline One of: junior, mid, senior, staff. |
| scores | object | Optional 0-10 score per skill. Valid keys: discipline-mastery, code-quality, debugging, system-design, tech-decisions, data-performance, shipping-outcomes, production-ownership, domain-expertise, communication, mentoring, cross-functional, ai-output, ai-quality, ai-workflows. Omitted skills use the level baseline (junior 3, mid 5, senior 6, staff 7). |
